Switch Statement
Due to use of multiple if statements, the program becomes more complex and lengthy. To avoid such
problem, JavaScript provides switch statement. The switch statement executes certain statements
depending on user's choice. The case statement is used to define different cases where each case has
a unique label and a set of statements associated with it.
The syntax of the switch statement is given the following:
Syntax:
